A new method of synthesising nanoparticle-functionalised nanostructured materials via Aerosol Assisted Chemical Vapour Deposition (AACVD) has been developed. Co-deposition of Au nanoparticles with WO(3) nanoneedles has been used to deposit a sensing layer directly onto gas sensor substrates providing devices with a six-fold increase in response to low concentrations of a test analyte (ethanol).

Rh nanoneedles and nanorods have been generated with the help of functional molecules like hexamethylene tetraamine and tridecylamine (1:2 in mM scale) as effective capping agents for electrocatalytic studies. A noteworthy negative shift of the onset potential towards the electrooxidation of formic acid compared to that of bulk Rh from cyclic voltammetry along with current densities from curren...

A novel architecture of SnO(2) nanowall-arrays coated with rutile-TiO(2) nanoneedles is fabricated for the first time and envisaged in dye-sensitized solar cells. Devices constructed using these architectures showed a power conversion efficiency of 4.12%, which is the highest among the SnO(2) nanostructures grown on conducting substrates by wet chemical methods.

Porous silicon nanoneedles can map Cathepsin B activity across normal and tumor human esophageal mucosa. Assembling a peptide-based Cathepsin B cleavable sensor over a large array of nano-needles allows the discrimination of cancer cells from healthy ones in mixed culture. The same sensor applied to tissue can map Cathepsin B activity with high resolution across the tumor margin area of esophag...

Recessive Dystrophic Epidermolysis Bullosa is an autosomal recessive disorder caused by loss of function mutations in COL7A1 causing mucocutaneous blistering and scarring, with considerable morbidity mortality. A few early phase gene therapy trials have been reported as potential therapeutic approaches. The targeted nature base editing well suited to restore functionality RDEB, if supported eff...

In current paper we demonstrate the applicability of high viscous oligomeric alkoxide concentrates in fabrication of technologically interesting structures like nanometer diameter fibers (down to 200 nm), nanoneedles (tip radii 15-25 nm) and some micrometers wide linear surface structures. The approach is cost-effective and simple as it utilizes low-cost precursor materials (metal alkoxides) co...

A novel strategy for extremely durable, reliable, and selective in situ real-time determination of superoxide anion (O(2) (-)) based on direct electron transfer of a biomimetic superoxide dismutase (SOD), Mn(3)(PO(4))(2), at highly conductive TiO(2) nanoneedles is reported for the first time, and is further exploited for the determination of O(2) (-) from living normal and cancer ovary cells di...

Current applications of carbon-based supercapacitors are limited by their low energy density. One promising strategy to enhance the energy density is to couple metal oxides with carbon materials. In this study, a porous MnCo2O4.5 nanoneedle/carbon aerogel hybrid nanostructure was synthesized by assembling MnCo2O4.5 nanoneedle arrays on the surface of channel walls of hierarchical porous carbon ...
